How can randomization help to infer a cause
WebThe study performed both types of Mendelian Randomization analysis and found no evidence to suggest a causal association between triglycerides and diabetes phenotypes. So Mendelian Randomization is a useful tool for inferring causality with biomarkers. WebMany scientists believe that the ONLY way to establish causality is through randomized experiments. That is one reason why so many methods text books designate experiments and only experiments--as quantitative research. Other scholars think causal relations can only be established with numeric data.
